firebase-yarn-workspaces

Yarn workspaces + Firebase deployments made easy.

Problem

Firebase functions does not support deployment of dependencies from a monorepo structure. To use dependencies which are not published to a registry, dependency code must be copied into the functions directory & referenced accordingly, prior to running firebase deploy --functions.

Solution

npx firebase-yarn-workspaces --scope <FIREBASE_FUNCTIONS_WORKSPACE_NAME>

This command, run at the root of your monorepo:

1. Automatically builds a yarn dependency graph of workspaces used in your firebase functions package.json
2. Copies all necessary package code into a .firebase-yarn-workspaces tmp folder inside your firebase functions workspace
3. Modifies package.json in firebase functions workspace and in all nested dependencies to point to file: references

NOTE: Rollback of package.json changes is still TODO. Recommended use is currently only in an ephemeral environment, such as CI or in a pruned Turborepo 'out' folder (see examples)

Options

Examples

Local pruned Turborepo

A simple shell script, which:

• Prunes & builds your Turborepo into a clean /out dir
• Installs dependencies
• Copies & links packages via relative file path replacement in package.json
• Deploys to Firebase

#!/bin/sh
cd $PATH_TO_TURBOREPO_ROOT

echo 'Creating a pruned Turborepo'
yarn turbo prune --scope=$FUNCTIONS_PACKAGE_NAME

echo 'Copying Firebase config'
cp ./{.firebaserc,firebase.json} ./out

cd ./out

echo 'Installing dependencies'
yarn

echo 'Running Turbo build'
yarn turbo run build --scope=$FUNCTIONS_PACKAGE_NAME --include-dependencies --no-deps --no-cache

echo 'Running firebase-yarn-workspaces'
npx firebase-yarn-workspaces --scope=$FUNCTIONS_PACKAGE_NAME

echo 'Deploying'
firebase deploy --force --only functions

echo 'Cleaning up ./out folder'
rm -Rf ../out
